Title: Back light
Inventor: OKABE AKIRA
IPC: G02F1/1335
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To enhance incident efficiency to a transparent light guide member by making an angle formed between an incident face and light irradiating face of the light transparent member acuter than a specific value. SOLUTION: An angle 6 formed between an incident face 4 of a transparent light guide member 1 and a light irradiating face 5 of the light transparent member 1 is made acuter than 60 deg., so that a clearance between a cylindrical light source 2 and a cylindrical light source reflector 3 can be enlarged without varying a thickness of the transparent light guide member 1, enhancing incident efficiency to the transparent light guide member 1. A greater apparent thickness of the transparent light guide member 1 allows the enlargement of the clearance between the cylindrical light source 2 and the cylindrical light source reflector 3, thereby making it difficult that light reflected on the cylindrical light source reflector 3 irradiates the cylindrical light source 2.  Since it becomes difficult to obtain uniform brightness of the light irradiating face around the incident face as the angle 6 becomes smaller, it is preferable that the angle should be 20 deg. or more in practice.

Title: Method and apparatus for manufacturing rotor for motor
Inventor: HARASHIMA KATSUMI
IPC: H02K15/12
Filed: 1986-04-16
Abstract: PURPOSE:To prevent defective resin mold such as a cavity in the inside by gradually discharging a gas generated in a resin excellently from a gas vent groove when a rotor for a motor is resin-molded. CONSTITUTION:A gas generated in a resin during the curing of the resin on molding is passed through a resin injection path 44, pushing up the peripheral resin and intends to pass to the outside from a resin injection port 43, but a rigid ball 41 is pushed up in the direction of the resin injection port 43 from a rigid-ball susceptor 42 during the passage of the gas. Since the inside diameter of the resin injection port 43 is smaller than the outside diameter of the rigid ball 41, however, the rigid ball 41 blocks its midway of the resin injection path 44. Accordingly, the peripheral resin is caused to flow out of the resin injection port 43 by the pressure of the gas generated in the resin, thus preventing the generation of defective molding such as a cavity in the peripheral resin section.

Title: Mask for x-ray lithography
Inventor: OOHAYASHI HIDEHITO
IPC: H01L21/027
Filed: 1982-05-24
Abstract: PURPOSE:To obtain a mask for X-ray lithography which is reduced in alignment errors, excellent in chemical resistance and transparent to even a visible light, by employing a thin film constituted by diamond or a mixture of diamond and amorphous carbon. CONSTITUTION:Since diamond has the highest thermal conductivity in the known materials, the employment of diamond makes it possible to quickly transmits to the outside the heat absorbed by an X-ray absorber, such as Au or the like, which is formed on a transparency, and minimize the rise in temperature of a mask due to exposure. As a result, it is possible to prevent any alignment error of a pattern. Moreover, since the mask is constituted by a transparent thin film, a visible light can be employed for alignment. To obtain an X-ray lithography mask, it is effective to form a transparent film constituted by diamond and amorphous carbon by employing magnetron sputtering or ion beam sputtering. Thus, a mask is obtained which has a sufficiently high film strength and an excellent light-transmitting property.
